Help us decide if we should be preparing to meet ET and aliens now, rather than later, at our Nature Live Night on Thursday 29 April

Is There Anybody Out There? is the subject of our Nature Live Night evening debate this week on 29 April and is a must for anyone interested in other planets and the possibility of extra-terrestrial life. Expect otherworldy topics on the agenda like the evidence (or not) for life on Martian meteorites, what will aliens look like, are aliens already here in a shadowy biosphere, Earth-like planets, and planetary protection.

We'll bring you together with astrobiologists and meteorite researchers to catch up with the latest news on the search for alien worlds. And we'll be debating how our actions in other worlds could affect life as yet undiscovered, as we ask the question 'should we actually be trying to find aliens'? Some, like Stephen Hawking, caution against this. See the recent BBC coverage of Stephen Hawking's warning of making contact with aliens.

The debate rockets off at 7pm in the Darwin Centre Attenborough Studio, and arrive at 6.30ish for a drink beforehand. The bar is open during the event. Book tickets (£6) online.

What would you tell an ET if you met one tomorrow? Come to the event and share your thoughts with other Earthlings.

Prepare to get spaced....
